Amine antioxidants are a type of “hindered amines” (HALS.) antioxidants. In order to prevent or inhibit the chain initiation reaction and chain growth reaction by capturing peroxyl radicals, thereby terminating the free radical chain reaction and achieving the purpose of preventing oxidation. Hindered amine light stabilizers can be used in polyolefin materials, cross-linked polyethylene, olefin copolymers, PS, PA, PU, soft PVC, etc., especially in thin plastic products and silk fabrics, showing excellent anti-photoaging effects; they can also be used It is suitable for most polymers, including PP products such as injection molding, film materials, and tapes. It can also be used as a light stabilizer in polyacetal, polyamide, and styrene polymers.UV absorber, widely used in PE, PVC, PP, PS, PC, EVA, organic glass, etc.; can also be used in dry phenolic and alkyd varnishes, polyurethane, acrylic, epoxy and other air drying Products and automotive refinishing paint, powder coatings, polyurethane, rubber products, etc.
